3Set Light Source 3.1Type of Light Source Ambient Light Environment light is a ubiquitous light. The light emitted by the ambient light source is considered to come from any direction. Therefore, when you only specify the ambient light for the scenario, all objects, regardless of the normal vector, will show the same degree of light and shade. Point Light Source The light emitted by such a light source comes from the same point and emits radiation in all directions, as shown in 5.3-

program handle and the uniform variable name. If the function is successfully called, the index value is returned. If the function fails,-1 is returned. It is also important to check the returned value for errors. This ensures that the shader value is correctly updated. In both cases, the function fails to be called. The first one is the misspelling of the variable name or the optimization operation performed by compiler. In this case, the correct in

Details about the Texturing texture of OpenGL ES 3.0 (2), opengltexturing Texture Filtering and Mipmapping Texture Filtering and multi-level Texture We have already introduced the 2D texture of a single 2D image. This article mainly describes multi-level textures. Texture coordinates are used to generate a 2D index. When the zoom-in and zoom-out values are set to GL_NEAREST, a single texture will be matched
